We also have a world famous and unrivalled range of
Photomultiplier Tubes and Modules.
The signal, [S.sub.f]([[lambda].sub.0]), of an instrument (
photomultiplier tube or CCD) can be modeled using Eq.
12 when a chain reaction destroyed 7,000 of the 11,000
photomultiplier (PMT) tubes installed in the system to collect Cerenkov light for neutrino study.
The
photomultiplier tubes--422 of them so far--are the eyes of the Antarctic Muon and Neutrino Detector Array (AMANDA), an instrument whose mission is to detect elusive subatomic particles known as neutrinos arriving from space (SN: 10/5/91, p.
The heart of the unit is a
photomultiplier tube descended from the light-sensitive devices pioneered by Jakob Kunz and Joel Stebbins early in this century (S&T: May 1992, page 496).
We have a range of high-gain
photomultiplier tubes specifically designed for single photon counting applications.
The University of Tokyo said Tuesday it was continuing investigations into an accident Monday at its cosmic ray research body in Gifu Prefecture where more than half of the 11,000
photomultiplier tubes (PMTs) attached to a large neutrino detector were found broken.
31 Physical Review Letters, the duo described using a sensitive
photomultiplier tube and lenses to collect light from a metal sample as it was scanned with the STM tip.
